Question
1.You are in charge of designing a menu tree for navigating 1,250 books in a digital library. Present an argument of whether the menu should have larger depth (number of levels) or breadth (number of items per level).2.Frequent menu users can become annoyed if they must make several menu selections to complete a simple task. Suggest two ways you can refine the menu approach to accommodate expert or frequent users.
3.Provide three examples of an application where menu selection and form fill-in are more appropriate than a direct-manipulation strategy.
4.Produce a thoughtful argument about what role natural-language interaction (NLI) should have in user interfaces.
5.Abbreviations for commands are often attractive for power users. Describe three strategies that could be used to abbreviate a command set.
Explanation / Answer
1. Having a larger depth (number of levels) would be more beneficial because it gives the end user more ease of use to find what is most likely either one book or a classification of books. 2. (1) Have a direct search bar in addition to having a search-by-menu-option option. Searching by menu would be better for the newer user, but a direct search bar may be better for the experienced user. (2) Allow abbreviated commands to quicken tasks 3. (1) looking for something specific but don't know exactly what you want, (2) looking for something satisfying certain conditions, and (3) filling out specific details and not leaving anything to generalities 4. NLI should play a role in many computer-human interfaces because of their speed and ease of use. It's difficult to implement, however, because there are a lot of similar inputs that could be interpreted to widely different results 5. (1) abbreviate command sets into compact commands making them easy to use for power users, (2) abbreviate command sets into commands that are easy to remember for near-power users, (3) abbreviate/use command sets into commands that still make sense to a newer user, but are quick to use for an advanced user
